NAME

File::Find::Object - An object oriented File::Find replacement

VERSION

version v0.3.2

SYNOPSIS

    use File::Find::Object;
    my $tree = File::Find::Object->new({}, @targets);

    while (my $r = $tree->next()) {
        print $r ."\n";
    }

DESCRIPTION

File::Find::Object does the same job as File::Find but works like an object and with an iterator. As File::Find is not object oriented, one cannot perform multiple searches in the same application. The second problem of File::Find is its file processing: after starting its main loop, one cannot easily wait for another event and so get the next result.

With File::Find::Object you can get the next file by calling the next() function, but setting a callback is still possible.

FUNCTIONS

new

    my $ffo = File::Find::Object->new( { options }, @targets);

Create a new File::Find::Object object. @targets is the list of directories or files which the object should explore.

options

depth: Boolean - returns the directory content before the directory itself.
nocrossfs: Boolean - doesn't continue on filesystems different than the parent.
followlink: Boolean - follow symlinks when they point to a directory.
You can safely set this option to true as File::Find::Object does not follow the link if it detects a loop.
filter: Function reference - should point to a function returning TRUE or FALSE. This function is called with the filename to filter, if the function return FALSE, the file is skipped.
callback: Function reference - should point to a function, which would be called each time a new file is returned. The function is called with the current filename as an argument.

Returns the next file found by the File::Find::Object. It returns undef once the scan is completed.

item

Returns the current filename found by the File::Find::Object object, i.e: the last value returned by next().

next_obj

Like next() only returns the result as a convenient File::Find::Object::Result object. "$ff->next()" is equivalent to "$ff->next_obj()->path()".

item_obj

Like item() only returns the result as a convenient File::Find::Object::Result object. "$ff->item()" is equivalent to "$ff->item_obj()->path()".

$ff->set_traverse_to([@children])

Sets the children to traverse to from the current node. Useful for pruning items to traverse.

Accepts a single array reference.

Example:

    $ff->set_traverse_to([ grep { ! /\A\./ } @{ $ff->get_traverse_to }]);

$ff->prune()

Prunes the current directory. Equivalent to $ff->set_traverse_to([]).

[@children] = $ff->get_traverse_to()

Retrieves the children that will be traversed to. Returns a single array reference.

(Example under "set_traverse_to").

[@files] = $ff->get_current_node_files_list()

Gets all the files that appear in the current directory. This value remains constant for every node, even after traversal or calls to "set_traverse_to()" and is useful to use as the basis of the argument for "set_traverse_to()".

Returns a single array reference.
